PROCESS OF MANUFACTURING GAS.

To all wiiom it may concern:

Be it known that I, WILLIAM H. GONE, a subject of the King of Great Britain and Ireland, residing at Detroit, in the county of Wayne and Stateof Michigan, have invented' certain new Vand useful Improvements in Processes of Manufacturing Gas, of which vthe following is a specification, reference being had therein to the accompanying' drawings.

The invention relates to the manufacture of gas from bituminous coal or other fuels high in volatile matter, and it is the object ofthe invention to convert practically all the carbon and hydrocarbon intoa permanen and relatively rich gaseous product.

To this endv the invention consists in the process as hereinafter set forth.

The drawing illustrates diagrammatically an apparatus suitable for the carrying out of my improved process.

It is generally understood that the distillateformed by the coling of bituminous fuels containsa large percentage of tar and other Aheavy condensable hydrocarbon vapors which must be c liminated before the gas is in Acondition for use. This requires a complicated purifying apparatus,' WhileA a considerable percentage of the Weight of the fuel is thrown out in the form ot' tar and. is not available for the manufacture of gas. Vlith my improved process the, distillation of the volatiles from the fuel is carried on under such conditions as to result in/the yformation oi noncondensable gaseous products, and these are coinmingled With carbon-monoxid gas formed by the combustion and docomposition of the solid carbon in the fuel.

I preferably carry out my process by the use of the apparatus illustrated, in which AVA are two cupolasarranged side by side. Each of these cupolas is provided with a combustion chamber B in its lower portion, and above this chamber a distillation chamber C. Between these chambers is a twyer l) and at the upper en'd of said distillation chamber is a second tWyer E. The twyers D and E of the two' cupolas are cross-connected by valve-controlled conduits, and, as shown, I? is a conduit connecting the twyer E of the cupola A With thetwyer of the cupola A. 'llicse conduits F F- contain controlling valyes G G by Which either one oi the conduits 'may be closed or opened.

of the cupolasis arranged a twyer II,v and these -tWy'ers vare alternatively connected with an arr blast conduit I and a gascnduit J.' Valves K K are arranged to VVcontrol ftlrese connections.

The lower ends -of the cupolas are preier ably provided with a Waterseal L permitting the Withdrawal of the ashes from the `lcupolas and at the upper end vof each cupola is a conu duit M leading `to the stack and controlled by a valve or damper N.

O is a fuel charger for introducing' a meas.

ured quantity of the fuel into Une u per end of eachcupola, and P is a normal y closedr poking aperture. i A

In carrying out the process', a, suitable uantity of the fuel is first ignited in both of t e cupolas, and the valves are adjusted so as to connect bothlcupolas at their 'up' er ends with the stack and the twyers at t e lower ends With the air blast pi e I. A Active comA bustion isv maintained in. t e cupolas until the fuel therein is brought into a state of incann descence up to thc'le'vel of the twyer D.A The valves are then adjusted first to cut oil the stack connection and'then to establish communication between the twyer D of one cupola and' the tWyer E of thefadjacent cupola,

, and, in the adjustment-shown, the valve G.'

is opened to establish communication through theconduit I4, While the valve G closes the conduit F. Green fuel is then introduced from the charger O into the distillation chamber C of the 'cupola A, and the valves K -K are adjdsted so as to connect the twyer Il of the cu ola A With the as conduit J, and the with the air conduit I. With the parts in this position of adjust'- ment, the air entering through the tWyer II into the lower end of the cupola A will pass through the entire body of fuel Within this cupola, and will pass through the twyer E and conduit F to the tWyer D of the cupola A, and thence downward through the incandescent fuel to the tWyer H, which is in communication with `the gas conduitJ. Duringthis o eration active combustion'isfiirstproe duce in theeupola A', andthe4 products ofv this combustion, together Withv a certainv amount of 'Water vapor rising'from the Water seal, Will pass through the conduit D into the cupola A, Wherethe carbon-dioxid 'is reduced to carbon-monxid, v`and thewater vapor is decomposed to `forni carbonrnonoxid and hydrogen. y Atthe saine time, the .heat

of the incandescent fuel in` the cupola will be I communicated to the green fuel thereabove i in nthe chamber C, and the Volatile matter of Exit for thedistilllate the up or end of the distillation chamber iscut oil by thc closure of the valves N and G. Consequently it is forced downward into the incandescent fuel therebeneath where it is coininingled with the carbon'- nionoxid and hydrogen.

ln 'the passage of the vdistillate directly into and through the incandescent fuel the heavy and condensable products, such as the tars, will be broken up, a portion of the car-` bon being freed and united with the coke, While the remaining hydrocarbon will be changed .into the form of relatively perma- These will be commingled with the carbon-monoxid, andwill greatly enrich the latter. i

When the green fuel in 'the cupola A is opening the conduit F and-closing the conduit F, and at the same time coupling the twyer H for the cupola A with the air conduit and the corresponding tiyyer in the cupola A with the gas conduit. l` his Will cause the air entering the cupola A to passthrough the entire mass of fuel therein, causing active combustion therein, which will restore the heat lost by distillation and decomposition. lf necessary, the coked fuel in the distillation chamber may be broken up by poking, and this, as Well as the lfuel thercbeneath, will be brought toa state of incandcscence. ln the cupola A. a charge of green fuel is introduced into the distillation chamber and this the same process of simultaneousdistillation, decom o'sitiony of the carbondioxid and the cracliing up of the heavy hydrocarbons will be carried on in this cupola, resulting inthe production of a rich permanent gas. f

lonsidcring bothcupolas -asva\unit, it will be observed that active combustion is mainend, and coking and distillation at an inter-v mingled With the products of the active combustion and passing therewith into the "one of decomposition. The periodic rcversall restores the heat lost by decomposition and maintains the heat for distillation substantiallyfconstant, While the supply of fuel is renewed ,in the intermediate zone and the ash is removed at cach end.
